For the past two years, we’ve worked hard to bring readers cutting edge analysis of China’s military jet engine development. The motivations for our focus are clear. First, to the best of our knowledge, no other open source publications have performed this sort of in-depth analysis of Chinese military and commercial jet engine development. This analytical gap is simply too important to leave unfilled. Second, weakness in jet engine production increasingly threatens to imperil China’s rapid progress in other aerospace dimensions such as airframe design and avionics, which are moving ahead far more quickly. The “linchpin” status of aeroengines makes the subject vital to understand for anyone interested in the future trajectory of China’s military aviation development.
